Tristan Murail (born 11 March 1947) is a French composer associated with the "spectral" technique of composition.
Murail was born in Le Havre, France. His father, Gérard Murail, is a poet and his mother, Marie-Thérèse Barrois, a journalist. One of his brothers, Lorris Murail, and his younger sister Elvire Murail, a.k.a. Moka, are also writers, and his younger sister Marie-Aude Murail is a French children's writer.
Following his university studies in Arabic and economics, Murail attended the Paris Conservatory, where he studied composition with Olivier Messiaen from 1967 to 1972. He taught computer music and composition at IRCAM in Paris from 1991 to 1997. While there, he assisted in the development of Patchwork composition software. In 1973 he was a founding member of the Ensemble l'Itinéraire. From 1997 until 2010, he was a professor of composition at Columbia University in New York City.
Murail is associated with the "spectral" technique of composition, which involves the use of the fundamental properties of sound as a basis for harmony, as well as the use of spectral analysis, FM, RM, and AM synthesis as a method of deriving polyphony.
Major pieces by Murail include large orchestral pieces such as Gondwana, Time and Again and, more recently, Serendib and L'Esprit des dunes. Other pieces include his Désintégrations for 17 instruments and tape, Mémoire/Erosion for French horn and nine instruments Ethers for flute and ensemble, Winter Fragments for flute, clarinet, piano, violin, cello and electronics as well as Vampyr! for electric guitar.
